In life, by all accounts, William Penn, founder of the Province of Pennsylvania, was a good man. In death, however, this portly, English-born idealist has turned nasty—if the good sports fans of Philadelphia are to be believed. But Norman Foster has a plan to appease the spirits.

Norman Foster is expected to design a new skyscraper in downtown Philadelphia, according to sources cited by the Philly Inquirer. Media company Comcast has outgrown its current home in the city’s tallest building—Robert A.M. Stern‘s 975-foot-tall Comcast Center. Details of the planned tower are being guarded, but architecture critic Inga Saffron reported that Comcast is exploring plans to build a “vertical campus” including several new towers, potentially beginning with a new structure on a 1.5-acre vacant lot at the corner of 18th and Arch streets (indicated above). The site was previously approved for a 1,500-foot-tall tower in 2008 but Saffron said the new tower would likely be shorter. Developer John Gattuso of Liberty Property Trust told the Inquirer, “The tower will be as big as it needs to be.”
